Mine Mine valve Jiangsu Lan valve valve accessories

江苏兰 valve General Equipment Co., Ltd. is a professional research and development, production and sales of high-tech enterprises valve actuators main products are: a coal mine gas pumps and automation needed for a dedicated drainage valve configured ZB, QB series of mine flameproof electric valve actuators and ancillary KXBC series of mine used flameproof electric valve control box and a series of accessories. ZB-type valve actuators, for coal mining conditions of use specially designed and manufactured. ZB type Denso linear motion applicable valve plate valve, gate valve, with valves, sluice gates and the like; such as increased post-secondary reduction gear box valve can also be used to make 90-degree rotation of the valve plate, such as butterfly valves, dampers and so on.江苏兰 valve General Equipment Co., Ltd. products through a national certification explosion-proof electrical product quality supervision and inspection center, made explosion-proof certificate and coal safety certificate. Explosion-proof multi-turn electric actuator for opening and closing parts of linear motion valves, such as gate valves, diaphragm valves, piston valve, water valve and so on. For the valve open, close or adjust. Is the valve to realize remote control, centralized control of the essential drive and self-control. They have a full-featured, reliable performance, advanced control system, small size, light weight, ease of use and maintenance. Widely used in electric power, metallurgy, petroleum, chemical, paper, sewage treatment and other sectors. Protection Type: Outdoor for non-flammable, explosive and corrosive properties of the medium. Explosion-proof products dI and dIIBT4 two kinds, dI applicable to non-coal mining face; dIIBT4 used in factories, for environmental explosive gas mixtures IIA, IIB grade T1-T4 group was. Valve actuators 江苏兰 valve General Equipment Co., Ltd. is to achieve a valve program control, automation, and remote indispensable drives, its operation can be stroke, torque or axial thrust to control the size, with a small, easy operation characteristics, and can meet various control requirements. Electric actuators for the hand - electric switching mechanism: semi-automatic switch, lever handle switch required manual, the manual state to automatically run when electric. The structure shown in Figure 7. It consists of a handle, switch parts, upright bars, clutch, spring and other components. Takes handwheel, push the handle to manually direction switching elements raise the clutch and oppression spring. When the handle is pushed to a certain position, the clutch that is out of engagement with the worm wheel and the hand wheel, and stand upright pole worm end surface torsion effect BARS, prop clutch will not fall, you can let go of the handle switch is complete, a hand-wheel operation . The required electric operation, the motor will drive the worm wheel is rotated, the upright bars supported on the end face of the worm wheel fall i.e., the clutch is moved rapidly in the direction of the worm wheel under the effect of the compression spring, and engaged with the worm wheel, while the hand wheel is disengaged, automatically Manual to power state transitions.
